Eva Marie Cassidy was an American singer and musician. She was known for her interpretations of jazz, folk, and blues music, sung with a powerful, emotive soprano voice.

Although she had been honored by the Washington Area Music Association, she was virtually unknown outside her native Washington, D.C. area at the time of her death from melanoma at the age of 33 in 1996.

Gino Vannelli is a Canadian rock/jazz/fusion/pop vocalist, producer, performer and Hall of Fame songwriter. Amongst his extensive catalogue of diverse, sophisticated and often complex albums blending musical genres, Gino had several commercially successful songs in the 1970s and 1980s. His best-known singles include "People Gotta Move" (1974), "I Just Wanna Stop" (1978), "Living Inside Myself" (1981) and "Wild Horses" (1987). Gino is known for possessing a powerful, rich voice which is astonishingly well-preserved, his enthusiastic stage presence, and for the high caliber musicians with whom he chooses to employ/perform. Early on, he was known for his huge mane of dark curly hair and handsome features, yet he chose to spurn the sex symbol trope and the commercial pull in order to create the life and music that felt more authentic to him. https://www.musiclifemagazine.net/gino-vannelli-to-take-his-rightful-place-in-canadian-songwriters-hall-of-fame/
